A TTORNE) ARCHERY now SIGHT BACKGROUND OF THE INVENTION This inventionconcerns an archery bow sight. More particularly, it concerns an archerybow sight which combines a mirror in which an arrow is reflected with asighting means.

DESCRIPTION OF THE PRIOR ART In sighting a arrow in archery, an archercan sight along the tip of the arrow to the target. However, the archermust compensate for distance and for drift or windage. For this reason,it has been desirable to provide a sight which is adjustable fordistance and is simple to use. A sight of simple design is described inU. S. Pat. No. 2,378,391. A strip of felt and a strip of Celluloidsuperposed one upon the other and attached to an archery bow has athrust pin thrust transversely into the felt strip, to compensate fordistance and windage.

In the present state of the art, the arrow is directed by establishingtwo points to determine the line of flight. One point is established bya sight attached to the bow of the type described in the above U. S.Patent. The second point is formed by interacting tactile sensationsbetween the archers arrow hand and his facial parts. The area of theface thus contacted, is referred to as the anchor point. Clearly, thesights must accommodate the physical characteristics of the archer.Therefore, because the physical dimensions vary between differentarchers, and various bow strengths, conventional archery sights having afixed setting between the sighting apertures are ineffective.Accordingly, a second requirement for an archery sight is that it befree from dependence upon the physical characteristics of the archer.

SUMMARY OF THE INVENTION The preferred embodiment of the presentinvention which will be subsequently described in greater detail, isemployed with a bow useful for target practice or for hunting.

A mounting means such as a bracket is attached to the bow to hold thebow sight in an appropriate position. On the mounting means is attacheda mirror whose horizontal axis is substantially perpendicular to thatvertical plane containing the centerline of the arrow. The mirror may betilted or rotated about its horizontal axis. An adjustable sightingmeans is also attached to the same mounting means.

In a preferred embodiment, the sighting means comprises a verticalfilament which may be a cross-hair or wire which lies against the mirrorface and also lies in that vertical plane which contains the arrowcenterline. The vertical filament runs straight up into the targetpicture. When the image of the arrow is centered in the mirror, on thevertical cross-hair, the flight will lie in the vertical plane whichcontains the arrow centerline and vertical cross-hair. The horizontalmember of the sighting means comprises a blade shaped member which ismovable and extends from the vertical filament. The movable blade can beattached to a pivotable shaft whose axis is parallel to the horizontaland can be connected to an indicating means such as a pointer which canread on an calibrated means such as a scale or dial.

The calibrated means can carry indices and set marks which are fixed onthe mountingmeans or attached thereto. The calibrated means can be arange scale to determine the pointer position and thin blade 5 angle.

The method of using the bow sight of the invention involves insertingthe nock of the arrow in the bow string with the arrow pointing in thedirection of the target, with the arrow reflected in the mirror.Visually, the archer sights the target along the blade member with thetarget lined up with the vertical filament. The blade member is set at apredetermined angle tocompensate for the distance of the target from thearcher.

One object of the invention is to provide a bow sight for use in archerywhich is mounted on a bow which eliminates tactile and muscularsensations as principal factors of the aiming process.

Another object is to provide a bow sight comprising a mirror reflectingmeans to direct the arrow in a predetermined direction in combinationwith a sighting means.

A still further object of the present invention is to provide a sightingmeans comprising a vertical filament and a horizontal blade shapedmember which are used as a sighting plane and cross-hair sight toprovide for compensating for a predetermined distance or trajecto- Stillfurther objects and advantages of the present invention will readilyoccur to one skilled in the art to which the invention pertains uponreference to the following detailed description.

DESCRIPTION OF THE DRAWINGS in which like reference characters refer tolike parts throughout the several views and in which:

FIG. 1 is a view of the preferred archery bow sight. FIG. 2 is a sideview of FIG. 1;

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, FIG.1 shows the preferred archery bow sight comprising mounting bracket 10having attached thereto mirror 12 in which is reflected arrow 11. Alsoattached to the bracket 10 are a thin blade 13 attached to a pointer 14adapted to read on range scale 15 and vertical cross-hair 16. The archersights the arrow in the mirror and at the same time lines up the targetat the point in the sight where the cross-hair and the blade meet,tipping the bow until the eye of the archer sees only the nearest edgeof the blade, the pointer adjusting the angle of the blade having beenset to correspond to a predetermined distance.

FIG. 2 showing a side view of the bow sight, shows the pivot 17 of thethin blade and the pointer.

It will be noted that the bracket holds the bow at an angle oflabout 15to avoid visual interference with the bow string. However, the angle canbe from about 5 to about 30, preferably from about 10 to about 20.Normally, the bracket is mounted a little above midpoint on the bow or alittle above the point at which the 65 arrow crosses the bow.

The mirror is' normally made of glass, but other reflecting means can beused such as, for example, highly polished metal, stainless steel or thelike, plastic The description refers to the accompanying drawings orpolymeric material having a reflecting backing such as transparentcellulose ester with aluminum or silver deposited or coated thereon toprovide a mirrorv The vertical cross-hair can be any suitable filamentsuch as, for example, wire, hair, string, polymeric material, etc. Ifdesired, it can be blade shaped.

The blade, as used herein, is intended to include other sighting meanswhich would function to line up the line of sight along a plane in thesame manner and could be adapted to be adjusted to correspond with apredetermined angle or distance. For example, an adjustableunidirectional sighting plane comprising a sighting tube or two or moresighting rings on a pivoting shaft to provide a unidirectionaladjustable visual sighting means could be substituted for the blade, orsubstituted for the combination of blade and vertical cross-hair.

Normally any bow or arrow can be used. Also the material from which thebow sight, bow or arrow is constructed can vary widely. Plastic orpolymeric materials can be used.

The invention has been described in detail with particular reference topreferred embodiments thereof, but it will be understood that variationsand modifications can be affected within the spirit and scope of theinvention.
